I feel there were way to many big name bad guys in this movie and they were killed off way too easy because their were too many and so some of them did not get the screen time they should have gotten. The one that comes to mind first is Shockwave. What I mean is with Sentinel ending up being the true ultimate bad guy in this one and of course you still have others like Megs and Screamer in there, why even add Shockwave? He didnt do anything that was important to the story or the plot of the story. His Driller could have still did just what it did in the movie without him ever being involved, with Shockwave not there you would have had more time to better flesh out the Optimus, Megatron, Sentinel battle at the end and most importantly we would still have at least one big name Con (Shockwave) that could have truly been used in the 4th movie and get some well deserved screen time and be a major character to the plot. Am I wrong for thinking this way? Would anyone really have missed him if he was not there with the Driller and the Driller functioned on its own as it really did anyway?
